During the 1970s and the early 1980s, immunization practices in the United States were unchanged. Immunization against pertussis, tetanus, diphtheria, measles, mumps, rubella, and polio were routinely administered to children. Infections with these organisms declined dramatically. Nonetheless, research was vigorous, culminating in the 1980s in new vaccines and changes in immunization strategies and practices. This presentation will focus on these changes: universal hepatitis B immunization; two-dose schedule for the measles, mumps, rubella (MMR) vaccine, Hemophilus influenza type B vaccine for infants, acellular pertussis vaccine as booster immunizations, the inactivated polio vaccine, and the yet-to-be-licensed live varicella vaccine.

New vaccine developments will reflect achievements of the World Health Organization's (WHO) Expanded Programme on Immunization (EPI), as well as resistance from the public toward increasing numbers of vaccines. WHO's EPI program has concentrated on tuberculosis, diphtheria, tetanus, whooping cough, polio, and measles. 35 countries are attempting to control hepatitis B with universal vaccination. Now some countries are also recommending vaccination against Haemophilus influenza, mumps, and rubella. The complexity of multiple injections has prompted new research on acellular vaccines for pertussis, hepatitis A and B, varicella, and malaria. Combined vaccines and new adjuvants are also targets of intense research. Vaccines are a priority, because they are among the most cost-effective of medical interventions.

In October 1984 in Sweden, a phase II trial of Biken acellular Pertussis vaccine was started and in 1986, a phase III trial of the same vaccine was begun. During the phase III trial, there were three cases of deaths out of 1,385 of study children at two, four and ten weeks after the second dose of the vaccine, due to severe invasive bacterial infections such as H. influenzae, Pneumococcus, or Meningococcus infection. A number of arguments arose about the results of the Phase III trial. No one can either prove or disprove the association between invasive bacterial infection and administration of acellular pertussis vaccine. The purpose of this paper is to discuss the side effects of Biken acellular DPT vaccine. The pediatricians inquired about the physical status of the children who received Biken acellular DPT vaccine. During the observation period, three out of 940 infants suffered from infectious diseases. One suffered from measles, the other from varicella and the last from mumps. Our retrospective study did not reveal any severe invasive bacterial infection cases cases such as the ones experienced in Sweden.

Contrary to the regular immunization schedule for children, the majority of immunization are done in adulthood in case of special risks only, such as old age, chronic illness or exposure. The protection against a variety of communicable diseases has to be monitored and if necessary to be boosted regularly. Based on the routine vaccination scheme 1991 of the Federal Department of Public Health, the following vaccinations which are commercially available in Switzerland are discussed in this review: diphtheria, Haemophilus influenzae, hepatitis B, influenza, measles + mumps + rubella, meningococci, pertussis, pneumococci, poliomyelitis, tetanus, rabies, tuberculosis, varicella and tick encephalitis. Furthermore, the current recommendations are given for the prophylactic and therapeutic use of immunoglobuline preparations.

Immunization practice in 32 countries in Europe, North America, Japan, and Australia is reviewed. in most countries, immunization practices are set by the federal government which sometimes works with the private sector. Almost all countries routinely immunize against diphtheria, tetanus, whooping cough, polio, and measles. About half try to prevent rubella, several try to prevent mumps, usually in combination with measles and rubella (MMR). More than half use bacillus Calmette-Guerin (BGG) vaccine to prevent tuberculosis, and a few give Hemophilus Influenza type B polysaccharide. Poliomyelitis vaccine comes in 2 forms: 1) oral live attenuated (OPV) or injectable inactivated (IPV). OPV is more used, but there is a new "enhanced potency IPV." All countries except Japan give DPT in 3 doses during the 1st year of life. OPV is usually given at the same time that DPT is. Measles vaccine or MMR is usually given between 12 and 18 months of age. Primary vaccine failure occurs in 2-5% of people who get measles vaccine, but this may be enough to "sustain transmission." In most countries, the government provides for immunizing children. An exception in the US. In the UK, low coverage has taken place because of concern for adverse reactions (whooping cough) or lack of appreciation of the disease's impact (measles). Coverage against both measles and pertussis has improved in the UK lately. In each developed country, vaccines have had "spectacular" effects. However, there are too many contraindications and there is "undue fear of adverse events." Also, there are surveillance deficiencies, a lack of coordination, and countries vary in their commitment to "reduction/elimination targets." Varicella vaccine, respiratory syncytial virus vaccine, and rotavirus vaccine are being considered for universal use. Attempts are being made to improve the safety of some vaccine.

The resurgence of measles has highlighted concerns about U.S. programs for immunization in infants and children. In order to put the problems into perspective, this review will address such issues as the safety of pertussis vaccines; oral vs inactivated poliovirus vaccine; vaccines for measles-mumps-rubella, Hemophilus influenzae type B, and hepatitis B; and varicella vaccine.

A retrospective study was carried out to determine the effect of common childhood infectious diseases on the hemoglobin level of a cohort of Alaskan Eskimo children born between 1960 and 1962. Hemoglobin and health records were available on 308 children between 6-11 and 12-17 months of age. Additional records were available on 187 of these children at 18-23 months of age. Episodes of chickenpox, measles, pertussis, and lower respiratory infections were reviewed. Between 38 and 50% of infants between 6 and 23 months of age had hemoglobin levels below 11.0 g/dl. The mean hemoglobin level of infants 6-11 and 12-17 months of age decreased with increasing number of total infectious episodes occurring within the 3 months before hemoglobin measurement. This trend was not apparent for infants in the 18-23 months age interval nor were low hemoglobins predictive of illness during the 3 months after the hemoglobin determination. At the 6-11 and 12-17 month age interval the number of lower respiratory infectious were most significantly associated with a decreased hemoglobin value. These observations are consistent with more recent reports that document iron deficiency anemia among children with antecedent infections and again emphasize the role of infection in the development and maintenance of anemia in children about 1 year of age.

The coverage rates of six vaccines (BCG, polio, DPT, measles, mumps and varicella) and the prevalence of these diseases in Japan were investigated. It was found that 82.2% of children had been inoculated with BCG before their first birthday, and 85.4% were given two doses of polio vaccine before their second birthday. The high acceptance rates of these vaccines seem to be attributable to mass inoculations at health centers. On the other hand, the median age when the first dose of DPT vaccine was given was as late as 22 months. Mass administration of this vaccine during infancy should be performed since about one-quarter of the patients with diphtheria, pertussis or tetanus were less than one year old. The cumulative percentage for measles inoculation failed to reach 60% by the second birthday. Considering that the incidence of measles has not yet been satisfactory lowered and that infants under 23 months of age account for about one-half of this incidence, more children less than 18 months old should be immunized. The ineffective rate of varicella vaccine was found to be 18.2%, although reestimation of its effectiveness may be necessary.

The authors describe 2 new vaccines now available in France: one is the GenHevac, an hepatitis B vaccine, the first virus recombinant vaccine; the other one is the Typhim Vi, a polysaccharide typhoid vaccine. Three other vaccines are currently used in foreign countries and will be soon available: the Hemophilus influenzae vaccine, the acellular pertussis vaccine and the varicella vaccine. Rotavirus and Cytomegalovirus vaccines are studied for their clinical efficacy.

Using traditional spectral analysis and recently developed non-linear methods, we analyze the incidence of six childhood diseases in Copenhagen, Denmark. In three cases, measles, mumps, rubella, the dynamics suggest low dimensional chaos. Outbreaks of chicken pox, on the other hand, conform to an annual cycle with noise superimposed. The remaining diseases, pertussis and scarlet fever, remain problematic. The real epidemics are compared with the output of a Monte Carlo analog of the SEIR model for childhood infections. For measles, mumps, rubella, and chicken pox, we find substantial agreement between the model simulations and the data.
